Heavy rain overnight and this morning led to several mudflows at the volcano. Between these flows there were swarms of small volcano-tectonic earthquakes, which may be associated with the interaction of water and cooling lava. Overall 30 volcano-tectonic earthquakes, 2 rockfall signals, one hybrid earthquake, and 2 long period earthquakes were recorded between 16:00 yesterday and 16:00 this afternoon. Seismic signals associated with mudflows were recorded at 5 o'clock and 7'oclock this morning for about half an hour each time and at 9:40 this morning for about an hour.
Observations of the mudflow near Belham bridge were made at about 10:30 this morning. Water flowed over the bridge and spread out for a hundred meters either side on the golf course. This water was carrying pumice and silt but not many big logs. The bridge remains undamaged. Scientists also investigated the affects of the flows in Plymouth. There are new mudflow channels through the police station up to 15 meters wide and the channels through the secondary school have been greatly increased. Mudflow deposits a meter deep have surrounded the gas tanks at the Texaco station.
Dust levels were low at all sites today.
Residents are reminded that the volcano remains in a potentially active state, and that they should continue listening to Radio Montserrat in case there are sudden changes.
